Gertrudes Ruiz de Esparza and Agustin Marungo

My name is Robert Martinez and I am looking for Gertrudes Ruiz de Esparza and Agustin de Marungo who married circa 1700 in the Villa de Jerez area near Zacatecas. I am new here and my folder is at this address: http://www.nuestrosranchos.com/es/robmartinez.
